General Description<\/h3>\n\n\n\n

EC87XX series is designed for power sensitive applications. It includes a precision and high voltage input stage, an ultra-low-power bias current branch, and results in a ultra-low-power and low\u0002dropout linear regulator.
The EC87XX operates from an input voltage of VOUT+1V to 40V, consumes only 2.6\u03bcA of quiescent current, and offers 1% initial accuracy and SoftStart function.
At power startup, the output voltage overshoot is less than 100mV.
The EC87XX regulators is available in standard SOT89-3L, and SOT23-3L packages.<\/p>\n\n\n\n
